I-Chem* Storm Water Sampler

Collects a full one liter first flush grab sample into a 1000 ml Nalgene* HDPE sample bottle within the first minutes of storm water outfall flow. Floating ball valve automatically closes off sample port after bottle is full to prevent comingling with later run-off and volatile analyte loss. Meets EPA NPDES MSGP (Fed. Reg. FRL-6880-5 10/20/00) and most state general permit grab sampling requirements. Sample bottle is leakproof when closure is applied. Sampling device intended for one-time use. Use with I-CHEM Storm Water Mounting Kit (catalog number 842-98198).
